Well, we don't really know yet if they are hitting 2200 lumens. It's in the spec, but what about post-calibration... Also no laser pj except the Sony 5000 reaches into the 4000-5000 lumen range and given the cost of the 5000 I do not expect to get that amount of light output for a long time. Even though with my screen I definitely need it for better HDR.

I think the 870 is going to cost a lot more than just "a bit extra". What lumens do you expect the 870 to put out post-calibration?

Of course it needs to be confirmed, but if true it's a nice move by JVC that might please those with a very dim (or very bright) screen, as it means that the new JVCs might be adjusting the tonemapping not only according to the content (static HDR10 metadata), but also to the brightness level of a given setup (depending on zoom, iris, lamp mode, screen size, gain, lamp age, etc). Of course it would have to be set manually, but it would be better than having no correction, and it could be done according to taste (no meter needed). Still not much improvement to expect from a PQ point of view from 2-3 good custom curves, but simple and elegant. Far easier to use, that's for sure.
Take this with a pinch of salt, I'm only deducting from the menu, I could be wrong of course.
Great find! Yes, hopefully that is exactly what this setting is for. As many will recall, I only get low 40 nits in my setup with 4K BT2020 filter in place and zoomed for 2.40 AR. It would be great not to have to mess with custom curves and Vertex automation, and rather have all this functionality baked in. Assuming of course JVC's implementation is excellent. Hopefully that slider covers a large range (lots of granularity). If the feature is what we are thinking, it would help people a lot in low nit situations, as well as people that wanted to optimize their HDR viewing based on their preferences, such as running on low lamp with a smaller screen and so forth.
It seems that JVC has been paying attention to what the community has been doing to work around the shortcomings of Gamma D and the built-in curve, and the need for much greater flexibility - again, assuming this feature is what we think. I do not think you can do custom curves like this with the Sony, automatically or manually - which gives the JVC a big advantage especially for low nit set ups.

LOL! I was thinking the same thing. I know it was posted somewhere - but does anyone know where the HWD dimensions are for the NX9?

A shame about the bright corner issue. Does this problem occur on the 4500/Z1 and if not why does it occur on these 4K models?
Thank you for your report and impressions.
I've quite confident that the banding Ran reported will be resolved in production units. After all, none of their current units or 4500 have this issue. I would think they'd realize that no one would accept a unit with that type of banding. Now if they said these were production units, I'd be a little concerned. But if anything, it was just the opposite. From the sounds of it it seems these units were rushed to get ready for a public showing. Like anything I'm sure the team would have liked "just two more weeks", but eventually the deadline to show it publicly must come. Hence the dynamic iris was not even working, and of course they'd have that working for production units. Bottom line is that it looks to me like this is a very early cut and there's a lot of work still to do, which is a good thing really.
Regarding what you said about bright corners - unless I misunderstood, Ran did NOT report that this unit suffered from bright corners. Now that I think about it, he did not comment on it one way or the other. Rather, he raised the general concern about bright corners that have been with DILA (and SXRD version) for years and years, and asked when we can expect them to be gone for good.

I would not expect JVC to lay out their road map on projector design. We will have reviews that show us exactly what the units are getting and good numbers are all any of us really need. I don't plan to try and build a projector and compete.
We will also learn exactly what the lens can resolve, once someone can show a 4K test pattern.
I'm curious why you are wondering what the lens can resolve. Earlier you said its the same exact lens from the 4500, and that the 4500 is stellar and can resolve the full 4K. So I'd expect no less. Then again, it will be reassuring for someone to actual confirm it, since these are new chips and a new design.

Indeed! Especially if the feature Manni pointed out is what we think it may be, allowing a way for us to tell the unit what our peak brightness is (in a range from super dim to super bright, hopefully) and have it adjust the curve for that as well as tone mapping based on static meta data. Even cooler would be if the unit would be able to measure its own brightness and set the slider based on the measurements. Who knows, maybe this type of HDR tuning will be part of the improved auto-calibration these units are rumored to have.
